Hi Art,

I don't know your specific voltage requirements from your message but could
you use a super-cap or regular capacitor in this situation? (As long as you
do the tolerance analysis and your calculations homework.)

Are you able to provide more details about your application?

Regards,

Ken Pergola

Subject: [OT]: small rechargable betteries??


I'm looking for some small rechargeable batteries. I only need 10 or 20
ma/hours, but they have to be small and stackable so I can get higher
voltages.

I found 1/2 N cells, they are still a little larger than I'd like.

I need brief (nanosecond to microsecond) ability to produce 3 ma or just a
tad more...so the battery backup cells won't work becsuse they are rated
for .2 ma and lower.

Any other candidates?

Thanks,

Art
